What to do
Operators must perform an initial inspection within 90 days after 14 February 2023 or before exceeding 22,500 engine flight hours, whichever is later, and then repeat inspections every 4,500 engine flight hours. If damage is found, inspection intervals must be shortened or the affected parts replaced before further flight as specified. Replacement of the blade set and disc is mandatory if damage affects more than 29 blades during on-wing inspection or any damage is found during in-shop inspection.
Summary
EASA Airworthiness Directive 2023-0027 is an airworthiness directive addressing inspection requirements for Rolls-Royce Trent 1000 series engines, specifically the low pressure turbine stage 1 blade assemblies with Part Number FW68788. The directive mandates repetitive inspections to detect cracking and separation in blade pairs welded at the outer shroud, which could affect engine vibration and safety.
What changed
EASA Airworthiness Directive 2023-0027 introduces new inspection requirements for the low pressure turbine stage 1 blades on Trent 1000 engines. It requires initial and repetitive inspections at specified intervals and mandates replacement of blade sets and discs if damage exceeds defined thresholds. This is a new directive and does not supersede any previous ADs.
Why it matters
This directive is critical for aviation professionals because undetected cracking or separation in the low pressure turbine blades can lead to blade failure and release of high-energy debris, potentially causing damage to the engine and reduced aircraft control. Operators and maintenance organizations must comply to ensure continued airworthiness and flight safety.
